     CONSTITUTION: In order to obtain the captioned small-size ingot which is rolled and replenished  into the melting pan of a die-casting machine or the like, the mold 6 closed with split patterns 9a,  9b is put in the chain line position of the ladle in molten metal and further the bold chain line position of the shank 40 in the molten metal immediately after the mold 6 stops at the angle I. This  causes a fixed amount of the molten metal supplied into a pouring funnel 21 to be filled into a  cavity 7 and sprue 8 through the short sprue 8 of the mold 6 communicating with this. While  producing a chilled layer from the surface layer with the water cooling of the mold 6, the molten  metal advances to angles II, III. During this time, the sprue is closed and cooled by a plate 18 and  the unfrozen molten metal in the central part freezes and deposits on the inside surface of the surface layer owing to the revolution about the axis 3, thereby becoming spherical ingot. At this  time, the shrinkage cavity produced in the inside is made vacuum so that virtually no unevenness  is produced on the outside surface. The split patterns open by cams 13, 15 and gravity, through  which the product rolls out at the angle IV.

Title: Engine testing method attached by learning operation
Inventor: TAKAHASHI MASAMI
IPC: G01M15/04
Filed: 1984-04-12
Abstract: PURPOSE:To achieve a higher reproducibility of testing by correcting control values sequentially based on values actually measured by learning operation beforehand until the delay in the response is within an allowable range to make dynamic characteristic of the engine follow the target value accurately. CONSTITUTION:The first learning operation is conducted with the target value as the first control value to obtain a series of actually measured values at each fixed time and it is determined whether the delay in the response is within an allowable range or not in the dynamic characteristic of the engine. When it is not within the allowable range, a series of control values are corrected by the series of actually measured values. Then, the series of control values thus corrected are applied to an engine controller to conduct the second learning operation. New series of actually measured values are obtained to repeat the judgement. Thereafter, a trail test is conducted until the delays in the response all meet the allowable range. The main test is conducted using the series of control values finally obtained. Thus, the dynamic characteristic of the engine follows the target value within the allowable range to obtain a high reproducibility.

Filed: 1994-04-11
Abstract: PURPOSE:To provide a SAW matched filter for a demodulator of an SS communication system which eliminates its loss to need no external amplifier and also eliminates the effect of reflected waves to reduce its error rate. CONSTITUTION:A SAW matched filter 1 constructs a demodulator which inputs an SS signal that is produced by modulating a PN code needed as a spread code with an information signal and applying the two phase modulation to a carrier by the modulated signal and then demodulating the information signal. Meanwhile the filter 1 consists of an input electrode which inputs the SS signal and a surface acoustic wave element having the serial interdigital electrode patterns 12a and 12b where the reference signals equal to one cycle of the PN code are written. When the SS signal is inputted, the correlative peak signals different from each other by one cycle are transmitted from both patterns 12a and 12b every time the matching of cycles is secured between the SS signal and the PN code. Then both peak signals undergo the delay detection.
